Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water resistant board support structure provided in front of a rising portion from a flat roof floor such as a parapet or a rooftop tower.

[0002]

2. Description of the Related Art A waterproofing treatment for a flat roof is described with reference to FIG. 1, in which a waterproof layer 4 is formed on a rising portion 2 following a floor waterproof layer 3. A pressing material layer 5 is formed on the upper surface of the waterproof layer 3 of the floor 1, and a water resistant board 6 for protecting the waterproof layer 4 is provided on the front surface of the rising waterproof layer 4.

The water resistant board 6 is supported at its upper and lower ends by upper and lower holders 11 and 12. Upper holder 1
1 is fixed to the mounting member 7 of the headstock 8 as shown in FIG.
As shown in FIG. 9, it is fixed to the attachment member 14 of the draining plate 13, or is fixed to a member different from those 7 and 14. On the other hand, the lower holder 12 is fixed to the floor 1.

[0004]

In recent years, as the structure for protecting the waterproof layer 4 of the rising portion 2 with the water resistant board 6 has become popular in the construction industry, the same structure can be obtained even when the rising portion 2 reaches 1 m or more. The number of examples adopted has increased. On the other hand, since the flat roof is located at a high place, it is exposed to a strong wind, and a considerable wind pressure is also applied to the water resistant board 6.

At this time, the water resistant board 6 has a width of, for example, 30 to 100 cm, and if its height exceeds 60 cm, it may be damaged by wind pressure and the upper and lower holders 11 and 12 may be poorly supported. For this reason, conventionally, a heat insulating material that can act as a buffer is interposed between the front surface of the rising portion 2 and the rear surface of the water resistant board 6, and this heat insulating material suppresses the bending of the water resistant board 6 due to wind pressure. .

However, in the support means using the heat insulating material, the supporting force varies depending on the hardness of the heat insulating material, and
Supporting the upper and lower ends of the water resistant board 6 is also difficult to apply uniformly over the entire length, and is usually uneven. Therefore, due to the imbalance of the supporting forces, there is a possibility that the water resistant board 6 is partially bent and damaged when subjected to wind pressure.

Further, since there is not a small amount of water intruding between the rising portion 2 and the water resistant board 6, when the heat insulating material absorbs water, the strength of the heat insulating material is lowered and the water resistant board 6 is absorbed.
May not play a reinforcing role.

Under the above circumstances, it is an object of the present invention to reliably support a water resistant board so that it can withstand wind pressure.

[0009]

In order to solve the above-mentioned problems, according to the present invention, in the support structure of the waterproof board for protection of the rising waterproof layer in the waterproof treatment of the above-mentioned flat roof, The point is the structure of.

One bracket 20 is fixed to the front surface of the rising portion 2. The one bracket 20
The other bracket 3 which is long in the lateral direction of the rising portion 2
0 is mounted so that it can move in the front-back direction, and
It can be fixed at the moving position of. The front edge of the other bracket 30 is in contact with the rear surface of the water resistant board 6.

In the structure of the water resistant board support structure, an anchor bolt 23 projecting forward is provided on the front surface of the rising portion 2 instead of the above point, and a bracket 40 that abuts the water resistant board 6 is attached to the anchor bolt 23. It is mounted so that it can move in the front-back direction , and the required movement position
It can also be fixed in place . At this time, the through hole 4a of the rising portion 2 front waterproof layer 4 of the anchor bolt 23
It is preferable that the sealing material 42 be filled with the sealing material 42 and that the sealing material 42 be pressed toward the rising portion 2 side by the nut 44 threaded through the anchor bolt 23.

Further, in each of the above constructions, the front edges of the other bracket 30 and the bracket 40 can be fixed to the rear surface of the water resistant board 6.

[0013]

In the water-resistant board supporting structure according to the present invention having such a structure, one bracket 20 is fixed to the required height of the front surface of the rising portion with screws or the like according to the height of the water-resistant board. Then, the other bracket 30 is adjusted so that its front edge comes into contact with the rear surface of the water resistant board 6, and is fixed by a screw or the like.

While fixing both brackets 20 and 30 to the rising portion 2 along its lateral direction, or after fixing them,
The water resistant board 6 is supported by the upper and lower holders 11 and 12. As a result, the required position in the height direction of the rear surface of the water resistant board 6 contacts the bracket 30 and does not bend even if wind pressure is applied.

Further, in the water resistant board supporting structure having the anchor bolts 23 as a component, the anchor bolts 23 are provided at required heights on the front surface of the rising portion 2 at required lateral intervals, and the brackets 40 are attached to the anchor bolts 23. . The contact between the front edge of the bracket 40 and the rear surface of the water resistant board 6 is adjusted at the position where the bracket 40 is attached to the anchor bolt 23. The bracket 40 prevents the water resistant board 6 from being bent, as described above. Even if the anchor bolt 23 penetrates the waterproof layer 4, if the sealing material 42 is filled, rainwater does not enter.

Further, by fixing the front edge of the other bracket to the rear surface of the water resistant board, it is possible to prevent the water resistant board from bending to the front side (opposite to the rising portion) when the pulsation of wind is negative.

[0017]

[Effects] Since the present invention is configured as described above, the following effects are exhibited.

In order to support the required position in the height direction of the water resistant board 6 with the brackets 30 and 40, for example, a height of 100
A water-resistant board 6 having a height of 50 cm, which can withstand the same wind pressure as the water-resistant board 6 having a height of 50 cm. Becomes

By adjusting the fixing positions of the brackets 30 and 40 with respect to the one bracket 20 or the anchor bolt 23, it is possible to cope with the change in the distance between the front surface of the rising portion 2 and the rear surface of the water resistant board 6, and to secure the water resistant board 6. Can support. This is very effective because it is very difficult to construct the front surface of the rising portion 2 straight, and in general, it is meandering and the distance between the front surface and the water resistant board 6 is uneven, which is very effective.

The brackets 20, 30, 40 can be made of high-strength products such as metal plates and plastic plates, and there is no fear that the strength will decrease due to invading water.

Anchor bolt 2 with sealing material 42
If the through hole 4a of No. 3 is closed, the waterproof does not enter.

By fixing the brackets 30 and 40 and the water resistant board 6 to each other, it is possible to more reliably prevent the water resistant board 6 from bending forward and backward.
